IMPROVEMENT IN CCOKING-STOVES.

To alt whom it may concern:

Be it known that I, GEORGE ROBERTS, ofthe city of Montreal, in thedistrict of Montreal, in the Province of Quebec, Dominion of Canada,bricklayer, have invented new and useful Improvements in Stoves andFurnaces; a-nd I do hereby declare that the following is a full, clear,and exact description of the same, reference being had the annexeddrawing, where- Figure 1 represents a front elevation of the stove..Fig. 2 represents a side elevation of the stove. Fig. 3 represents ahorizontal section on line A B, Fig. 1. Fig. 4 represents a verticalsection on line C D, Fig. 3. Fig. 5 represents a section of dampers.Fig. 6 represents a view of dampers, and Fin". 7 represents a sectionalelevation through the line E F, Fig. 4.

This invention relates to improvements on stoves and furnaces generally,whereby peat, or soft or bituminous coa-l may be burned rwithoutexperiencing any of the ordinary annoyances, or the iiues and pipesbeing choked up, etc., as by this invention the smoke Aarising from thepea-t or coal is wholly, or in a very great measure, consumed, theheated air being concentrated in one spot in the center of the stove,whence it may be diffused in any way desired. rlhe invention may also beapplied to steam-boilers, or in any other case where it is desirablethat the smoke should be consumed.

In the drawing similar letters of reference indicate like parts.

c .is the casing of the stove, of any convenient or suitable form, a1being the top plate of stove.

b is a partition cutting oit from the main part of the stove a space,which is further divided transversely into three parts, shown at b1 b2b3, by partitions c c, and inclosed on top by a plate, d, Fig. 7.Suspended from d and nearly filling the upper part of the space I)2 isthe ire-pot c, preferably of the shape shown, and provided with ashaking-and-dumping grate of the ordinary description, and ash-pit c, asshown, for the reception and removal of dust, ashes, &c. The fire is fedthrough an aperture (provided with a damper) in the top plate a 5 butmay be arranged in any other suitable way. The spaces or air-chambers b1and b3 are still further divided up by diaphragms j' running at rightangles to the partitions c and extending nearly as high as the plate d.Between this diaphragm f and the iront of the stove are arranged in eachof the chambers bl b3 two pipes, g and lL, for the -admission of coldair; g, the lower one, admitting the air to the chamber b2 just belowthe grate, and h, the upper one provided, if desired, with a casing,admitting the cold air through the plate d above the iire-pot c. t' areair-ducts for the admission of cold air into the chambers b1 and b3, andk k1 k2, apertures for the admission of small streams of cold air to thetop oi the fire-pot. The pipes g g It It have their ends provided withmouth -pieces h2 as shown in Figs. 1 and 3, and all the outside openingsare provided with dampers l, shown more clearly in Fig. 1, hung onpivots Z1, andprovided on their lower sides with projecting ledges Z2,arranged so that when the damper is open the under side of the ledge L2being iiush with the upper edge ofthe air-duct may act as aconductor tothe air. m m are two ovens with doors m mf, divided from eachother by adiaphragm, a, which, with the divisions al a2 on the lower part of whichthe ovens are supported, form the iiue ofthe ordinary type, arranged asshown in Fig. 4, with a damper, o. The ovens are constructed 'so thatthey may easily be taken out for the purpose of cleaning the ue. Adamper, @,actuated by a handle, p', is placed behind the lire-pot,arranged so that it will, when closed, prevent the draught of the firegoing directly to the flue.

I will now proceed to describe the operation of my invention. Thefire-pot c being iilled with fuel is lighted in the usual way, the pipesy g admitting the air to the bottom of the grate, and the dampers p ando conducting the smoke direct to the iiue being opened, and the otherpipes lL 7L and air-ducts being closed, so soon as the rire has heatedthe air in the stove to a suiiiciently high temperature cold air may beadmitted to the top of the iire-pot through the pipes la h, the casin gh1 keeping the air cool, and, ifdesired, through the apertures k k1 k2,the damper p being closed to turn the tire to meet the several streamsof cold air, the form ofthe mouth-pieces ofthe pipe and of the differentapertures giving the streams a fan-like. shape; immediately on contactwith the ire they ignite and so consume theproducts of combustion, thecurrents 0f heated air converging again to the center, whence they maybe carried offforheating purposes, ifdesired. Should any, however,remain they are carried down behind the ovens and into the iue in theusual way.

The cold air meanwhile` being admitted by the ducts i z' into thechambers D153 is there warmed by contact with the partitions c c, and,passing over the top of the diaphragins f, escapes through theperforations in the lower part of the partition b in the chambers b1 andb3, thus both heating the ovens and tending` to increase the draught tothe flue. Behind the fire-pot e the partition b is perforated in itsupper part in order that the air may be thoroughly heated by contactwith the fire-pot before passing through the perforations.

WHaving thus'V described Vthe eons'tructionand' operation of myinvention, to which I have given the name of the peat and coalsmoke-consumer. what I claim as my invention, and wish secured byLetters Patent is, the new and useful iinproveinents on stoves andfurnaces, as follows:

1. The novel combination of the plate el and lire-pot e, with pipes gand 71., arranged and operating substantially in the manner and for thepurpose described.

2. The perforated division b, partitions c, diaphraginsf, and air-ductst', constructed, arranged, and operating substantially as described.

3. The novel damper with pivot Z1 and ledge Z2, constructed as and forthe purpose described.

4. The novel combination ofthe pipes g and h with mouth-pieces 71,2 andapertures lc k1 k2, constructed, arranged, and operating asand Vfor the't purpose described.
